Okay, here's is what I want to do.  I have an unsigned char global
variable and want to store it the *entire* vga memory.  I'm using mode
13h, so it's a 64000 byte memory buffer.  I've looked at movedata and
memset and both have segfaulted on me.  I want to call one function that
takes care of this instead of looping 64000 times farpoking the
variable.  Thanks for any info - this might even be a question for the
faq, I'm not sure, I checked it but did not find anything enlightening.
